FX AC in New Mehran VX cng

I want to Install AC in my new mehran which will be delivered in May 2007. Is it possible to install FX AC (2nd Hand) in New Mehran. and what will be its performance. Or a newer one of DENSO (which is being fitted by Pak suzuki) should be installed?
Pls gave me an expert opinion keeping in view that mehran is not fit for AC so why to have a costly solution
Regards

Though I am not a expert... what I can tell you is only my experience.... as far as installing a used ac... well it depends on the condition of that particular compressor... if is it still good and alive... i see no harm.

as far as you said Mehran is not fit for ac... well I do agree its not fair to but such a heavy burden on a 800 cc poor thing... and specially if it runs on CNG... but I have a 2004 Mehran... and till now there no problem with it both the car and the ac...all you have to is to be a little careful while driving in heavy traffic, you dont want your car to get very hot... And I guess they even have ac in a 660cc car.

well i did change mine... in fact I had decided to change those even before i bought the car... as i was very much sure that I will be driving alot on motorway. and i am happy about my decision... its been almost 3 years and 50,000 km and not a single puncture.
